After Pearl Harbor, it’s time for the US to strike back ~

Avery Abernethy, 24 July 2017

After the Japanese destroyed most of the US Pacific Fleet at Pearl Harbor on December 7, 1941 the US Naval Command and President Roosevelt were under tremendous pressure to position the US Carriers into a defensive position. Some argued the carriers should defend Hawaii. Others suggested pulling the carriers back to protect the US West Coast. After taking command of the Pacific Fleet on December 31, 1941, Admiral Nimitz was responsible for how the US Fleet would be deployed.

Instead of a strict defensive deployment, Nimitz used the remaining US ships centered on the aircraft carriers to both ferry planes to Pacific outposts and also to launch raids against the Japanese. The decision to launch raids against Japan was a very ballsy move by Nimitz. The most famous raid was by Doolittle’s group from the Carrier Hornet. But a more extensive raid against the Gilbert Islands came first.

This is an after action report (AAR) from Order of Battle: World War 2 the US Pacific Campaign and the Marshalls – Gilbert Islands Raid scenario. I played this scenario as part of the US Pacific Campaign.

Before the start of the scenario, I had previously chosen to take the two radar technology upgrades. The radar technology purchases were useless in the earlier land scenarios, but better radar allows both planes and ships to locate bogies at much longer ranges. I knew the radar would be vital for the 1942 and later naval battles.

Upgrade Took Radar


The objectives for the scenario range from the easy to the very difficult. You can “win” the scenario by not having either of your two carriers sunk. Another secondary victory condition is not suffering damage to your carriers. Staying away from the Japanese islands and not performing the raid would achieve these objectives. The other three objectives are much harder. You get advantages in future scenarios if your forces can destroy the four Japanese oil depots and shoot down the Jap planes based on four widely separated air strips. The oil depots and air strips are known. The last secondary objective is to sink ten or more enemy ships. I don’t know how many Jap ships are out there nor do I know where they may be lurking.

Objectives on Map


If I kept my carriers in one group it would be almost impossible to destroy all of the Jap aircraft and oil depots. The targets are too far apart. I decided to split my carriers into two very small task forces: task force Black and task force Red. Both carriers have three air wings (one fighter, one dive bomber and one torpedo plane). Task Force (TF) Black starts with a carrier, a cruiser, two destroyers and a PT Boat. TF Red has a carrier and one cruiser. TF Black will hit the closest island and destroy the aircraft, oil depot, and any detected shipping. Then the PT Boat will be sent North to join TF Red while the rest of TF Black steams South.


TF Red has further to go to reach a launch point for its first target. TF Red will stay in the North and hit three islands in succession. TF Black will be steaming much further and is ordered to rejoin TF Red to jointly attack the last Japanese air strip and oil depot after they destroy their first two objectives.

There’s more to come later this week, so stay tuned, as the battle is just heating up
